Monsanto's Roundup Causing Evolution of "Super-Weeds" That Grow 3 Inches a Day

A new series of studies released by Weed Science this month finds at least 21 weed species have become resistant to the popular herbicide glyphosate (sold as Monsanto's Roundup), and a growing number survive multiple herbicides, so-called "super-weeds." The same selection pressure creating bacteria resistant to multiple antibiotics is leading to the rapid evolution of plants that survive modern herbicides. If the trend continues, yields could drop and food costs climb as weeds grow more difficult to uproot. Remember, Roundup is the most widely used herbicide in the world. Much of the modern food production system has come to rely on it -- and as it becomes harder and more expensive to get rid of weeds (and super-weeds) in a world where the market have grown accustomed to an artificially deflated cost of weed-killing, this Roundup trouble could cause global food prices to s...
